The expression for 4 times the number of cows plus 2 times the number of ducks can be represented mathematically as (4c + 2d), where (c) is the number of cows and (d) is the number of ducks. To find the total value, simply multiply the number of cows by 4 and the number of ducks by 2, then add the two results together. This gives you the total count based on the specified multipliers.
3 times 3 = 9 plus the number 3 = 12.
How about: 1 times 91 plus 4 = 95 or 7 times 13 plus 4 = 95
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
6n + 7n (= 13n)

18 is a solution to the equation 4 plus 7 times a number where the result is 9 times that number.
3 times 3 = 9 plus the number 3 = 12.
How about: 1 times 91 plus 4 = 95 or 7 times 13 plus 4 = 95
the number is 3 because 3 times 5 is 15 plus 2 is 17

6n + 7n = 13n
Because they are both multiples of two, so when they're added, the sum must be another multiple of two. (One group of twos plus another group of twos must be a new group of twos, just like one group of cows plus another group of cows must be a new group of cows.)
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
